Little money mining

1.

According to the current difficulty calculation, we can dig about 1.012 Laite coins a day. This is the average calculation result in the mine pool. If there is an efficient mine pool or solo, maybe more

litecoin (abbreviated as LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

design purpose

it is based on bitcoin protocol, but it is different from bitcoin in that even at the present stage, it can efficiently "mine" through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin

transactions

a peer-to-peer network similar to bitcoin handles lightcoin transactions, balances, and issues through a script workload proof scheme (when a sufficiently small hash value is found, the, A block will be created, and the lightcoin will be issued. The process of discovering the hash value and creating the block is called "mining"). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable for "mining" with graphics processor (GPU). FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

client

litecain is a free software project released under MIT / X11 license, which allows you to run, modify and the software according to your own needs. You can also release a modified version of the software if you like

the software is released in a completely transparent form, and users can independently verify the binary version and the corresponding source code

mine pool

the lightcoin is generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoins at one time. At present, the computing power of lightcoin is growing rapidly, and the miner can't find the mine through several computers. Therefore, it is necessary to join the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher

at present, the well-known mine pools include BTCC (original bitcoin China) mine pool, waltc.net fish pool (f2pool), wemineltc, coinotron, silverfish, liteguardian, litecoin pool.org, etc. But at present, the highest income is f2pool. Recently, it launched lightcoin theory income + 10% of mine pool subsidy = your actual income, which has attracted the attention of many miners and the instry

data block chain

litecoin block chain, compared with its competitor bitcoin, can handle larger transaction volume. Due to the more frequent generation of data blocks, the network can support more transactions without modifying the software in the future
as a result, businesses can obtain faster transaction confirmation, and they can still wait for more transaction confirmation when they sell large value procts

In fact, digital virtual currency is far from the above. Forbes magazine listed the top 30 virtual currencies in the market by their total market value and price as of 10:00 a.m. local time on the 27th. Caijing.com and venture capital Post said that there are at least 60 kinds of virtual currencies currently traded According to the Forbes report, bitcoin ranked first in market value and unit price. It was the lightcoin designed by Li Qiwei, a former Google programmer, that won "erlianya". In the past week up to the 27th, the price of lightcoin rose rapidly from $6 to $26, a considerable increase. The third to fifth place in the total market value are spot money, nominal money and prime money. The report counted the 24-hour gains as of the 27th. Almost all of the 30 currencies rose, with the biggest increase of the quark currency, reaching 278.55%. The report also said that almost all virtual currencies have taken a ride in the current round of bitcoin's rise, but most of them have poor business, with 8 companies with a total market value of less than $1 million and 19 companies with a unit price of less than $1

2.

In 2016, the global ranking of virtual currency is respectively as follows:

< H2 > bitcoin, Leyte, Ecuadorian, reborn, bitstock, doggy, Diablo, futurecoin, diandiancoin and Xingxing < H2 > first place: bitcoin

since its release in 2009, bitcoin has become the most well-known virtual currency. This virtual currency was developed by indivials or organizations under the pseudonym of "Nakamoto Tsung" (whose real identity has always been unknown), and is mainly used by online merchants. However, in recent years, some small physical merchants have begun to accept bitcoin payment. Through complex algorithms and a large number of computing resources, users can obtain bitcoin through "mining". Of course, they can also purchase bitcoin through exchanges or services like bitinstagnt and coinbase. The total amount of bitcoin that can be mined is about 21 million, while the current mining amount has exceeded 11 million. Bitcoin has attracted the attention of Western Union, MoneyGram and paypal. It is reported that these services are evaluating whether users are allowed to use bitcoin on their respective platforms

< H2 > second place: lightcoin

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte coin is divided into 100000000 smaller units, and the third place is defined by eight decimal places: Ecuadorian currency. In December 2014, Ecuador launched the "electronic currency system"

Ecuadorian currency, or EDC, which is a digital currency issued by the Central Bank of the government of Ecuador. In December 2014, the Ecuadorian market was launched, In 2015, the number of Ecuadorian currency members reached 500000, which will be recognized and sought after by investors after launching the European market and Asian market in 2015, and achieve a complete success. It will strongly launch the Chinese market at the end of September 2016, and will issue a limited number of 50 million pieces in China, which has a strong scarcity! This is an international hot topic with a wide range of admirers in the world. Historical currency is a kind of P2P digital code. Ecuadorian currency is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. Ecuadorian currency economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions

decentralized encrypted digital currency has no issuing institution, and it does not belong to any indivial, institution, bank or country, so it cannot be shut down. Ecuadorian coin mining machine is mining 24 hours a day, and the extracted Ecuadorian coin can be traded through the trading platform to obtain profits. Ecuadorian coin mining refers to the scrypt algorithm, The process of collecting and sorting the transaction information that has not been recognized by Ecuadorian currency in the past period of time, broadcasting to all nodes in the whole network, and finally being recognized by all nodes and getting Ecuadorian currency. Mining is the only way to issue new currency, which plays an important role in issuing new currency, maintaining Ecuadorian payment function and ensuring system security

Like bitcoin, XRP is a digital currency based on Mathematics and cryptography. However, unlike bitcoin, XRP has no real purpose. XRP has the main function of bridging currency and ensuring security in ripple system, among which the function of ensuring security is indispensable, This requires that all gateways participating in this protocol must hold a small amount of XRP

in theory, gateways don't need to buy many xrps, and their prices are very cheap. One XRP is only 0.4 cent (as of March 14, 2015, its price has risen to about 1 cent). Like bitcoin, the number of xrps can not be "over issued" (the total number is 100 billion), but since a small amount of xrps will be destroyed in each transaction, it means that the number of xrps will graally decrease. If ripple protocol can become the global mainstream payment protocol, the gateway's demand for XRP will be more extensive - the demand is strong but the quantity is decreasing, which will lead to the appreciation of XRP

< H2 > fifth place: bitstocks

bitstocks adopt an architecture similar to bitcoin blockchain. In the bitcoin blockchain architecture, each transaction data must be written from the previous transaction data, and new outputs are generated almost at the same time to be used for future transaction data writing. Each stroke can only be used once under certain conditions. Each transaction output contains the balance information of bitcoin, proving that it can be used for future transactions. In order not to proce bitcoin out of nothing, the write value of the transaction must be greater than the output value

bitcoin uses a simple script language to evaluate the situation that the balance is insufficient when the transaction is output; However, most of the transaction output only needs the holder's encrypted signature

< H2 > sixth place: dogcoin

dogcoin, some people call it "dogcoin", was born on December 8, 2013, based on the scrypt algorithm, is the second largest virtual currency in the world after bitcoin in the number of users [1]. Digital currency is a global currency initiated by non-governmental organizations. It does not belong to a certain country, but belongs to the whole mankind. It has the advantages of fast global transfer. For example, it can remit money from China to the United States in a few seconds, with low cost, and the total amount will not be increased at will like legal money, so the total amount is relatively stable

after the launch of dogcoin system, e to the help of reddit (the doge content on this website overflows horribly), the traffic shows an explosive development. However, in two weeks, dogcoin has launched a special blog and forum, with a market value of 100 million as of June 9, 2015. Because there is no pre dig, dog coin distribution is fair, charity, reward culture is popular, and user development is amazing and rapid. On June 9, 2015, the number of Dog Coin client addresses was 1.6 million, more than five times that of Wright coin; The number of active client addresses is 196000 in bitcoin, 83000 in dogcoin and 11000 in lightcoin; There are more than 150000 foreign Twitter users, 1.7 times of bitcoin and 6 times of lightcoin. Facebook likes are the same as bitcoin, far more than lightcoin [2]. The daily real transaction volume has been ranked in the top three of virtual currency for a long time, which is still not as good as the result obtained before the big platform [3]. The biggest value of the enterprise Internet era is the huge number of users. It took one year for the user base of dogcoin to reach one third of the number of bitcoin users, and the seventh place is lightcoin, which is four times the number of bitcoin users. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 8] In the metaphor of RMB, black money is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 22 million special solutions, so the upper limit of bitcoin is 22 million[ 8]

to mine the dark coin, you can download the special dark coin calculation tool, register various cooperative mine pool websites, fill the registered user name and password (miner user) into the calculation program, and then click the operation to officially start. After completing the installation of the darkcoin client, you can directly obtain a darkcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the Black Coin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, the personal dark coin will be completely lost

3. In line with the rigorous logic of problem-solving, we should first ask whether it is, then why
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow

Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers

bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods

bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

{rrrrrrr}

extended materials:

the founder of bitcoin:

on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed

bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money

trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data

the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes

in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura

Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm

bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards

in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information

to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak

at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher

at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece

the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation

6. Jinwowo group, based on the blockchain model architecture, does the analysis in the following way:
1 - data layer: data block, chain structure and time stamp
2 - network layer: P2P network, propagation mechanism, verification mechanism
3 - consensus layer: pow, POS, dpos
4 - incentive layer: issuance mechanism, distribution mechanism
5 - contract layer: script code, algorithm mechanism, smart contract
6-application layer: encapsulates various application scenarios
in the future, jinwowo group will focus on promoting the legal circulation and commercial application of big data with blockchain technology.

7. What do pow, POS and dpow mean
when it comes to blockchain, we must talk about its consensus mechanism. If we don't understand the consensus mechanism of blockchain, we can't understand the real meaning of blockchain. So, what about the consensus mechanism of today's blockchain
what is the consensus mechanism
what is consensus? Take its literal meaning, that is & quot; Common understanding & quot
people are different, not only in stature, appearance and ability, but also in culture, views, ideas, interests and so on
consensus, in short, is the consensus reached by members of a group in a certain aspect
we have learned that trust is a major pain point in the operation of society. Banks have their own credit system. In the past, the financial system only served a few entrepreneurs, because the establishment of credit system cost a lot. Later, Alipay had sesame credit. Credit has already been related to many aspects of life, credit card size, spending amount of flowers, sesame credit and high going abroad can be avoided. We are enjoying the convenience of credit
the essence of blockchain is decentralization, and the core of decentralization is consensus mechanism. The consensus mechanism on blockchain mainly solves the problems of who constructs the block and how to maintain the unity of blockchain
the goal of the blockchain consensus mechanism is to make all honest nodes save consistent blockchain views, while meeting two properties:
1) consistency: the prefix part of the blockchain saved by all honest nodes is exactly the same
2) effectiveness: the information released by an honest node will be recorded in its own blockchain by all other honest nodes
the confidence of blockchain is mainly reflected in the fact that users distributed in the blockchain do not need to trust the other party of the transaction or a centralized organization, and only need to trust the software system under the blockchain protocol to realize the transaction
what is the consensus mechanism? What do pow, POS and dpow mean
the necessity of consensus mechanism
in a distributed system, multiple hosts form a network cluster through asynchronous communication. In such an asynchronous system, state replication between hosts is needed to ensure that each host can reach a consensus. Error messages may appear in asynchronous systems and propagate continuously, so it is necessary to define fault-tolerant protocols in default unreliable asynchronous networks to ensure that all hosts reach a safe and reliable state consensus, which is the necessity of consensus mechanism
the premise of such self-confidence is the consensus mechanism of the blockchain, that is, in a market of mutual distrust, the sufficient and necessary condition for each node to reach an agreement is that each node will spontaneously and honestly abide by the pre-set rules in the agreement to judge the authenticity of each record for the sake of maximizing its own interests, Finally, the records judged to be true are recorded in the blockchain. Attachments-2018-08-9yy7vrha5b738e3d96021. JPG
in other words, if each node has its own independent interests and competes with each other, it is almost impossible for these nodes to conspire to cheat you, especially when they have public reputation in the network. Blockchain technology is the use of a set of mathematical algorithms based on consensus to establish & quot; Trust & quot; Network, so as to create new credit through technical endorsement rather than centralized credit institutions
Introction to several consensus mechanisms in today's blockchain
there are many consensus mechanisms in blockchain, but none of them is perfect, or suitable for all application scenarios
POW workload proof
each node in the whole system provides computing power (referred to as computing power) for the whole system. Through a competitive mechanism, the node with the best computing work can be rewarded by the system, that is, to complete the allocation of newly generated currency. It is simply understood that more work pays more. Currency blockchains such as bitcoin and LTC apply POW mechanism
advantages
completely decentralize the nodes to get in and out freely, the algorithm is simple, easy to realize, and the cost of destroying the system is huge. As long as the computing power of the network destroyer does not exceed 50% of the total computing power of the network, the transaction status of the network can reach an agreement
disadvantages
waste energy, which is the biggest disadvantage. It is difficult to shorten the block confirmation time, for example, bitcoin can only do 7 transactions per second, It is not suitable for commercial application. A new blockchain must find a different hash algorithm, or it will face bitcoin's computing power attack. It has high requirements on the performance of the nodes, and the network environment is prone to bifurcation. It needs to wait for multiple confirmations, and can not reach the final agreement
POS proof of equity
also known as proof of equity, which is similar to you deposit your property in the bank, This model will allocate interest to you according to the amount and time of cryptocurrency you hold< Advantages
low requirements for node performance and short consensus time
disadvantages
there is no final consistency, so checkpoint mechanism is needed to make up for the finality
dpow is an evolutionary scheme of pos. in conventional POW and POS, any newly added block needs to be confirmed by all nodes of the whole network, which greatly affects the efficiency
dpos is similar to the voting mechanism of modern board of directors, which elects representatives to vote and make decisions. The N selected accounting nodes are used for the creation, verification, signature and mutual supervision of new blocks, which greatly reces the time and computational cost of block creation and confirmation
advantages
greatly rece the number of nodes participating in verification and accounting, which can achieve second level consensus verification
disadvantages
sacrifice the concept of decentralization, which is not suitable for public chain
pbft practical Byzantine fault tolerance
practical Byzantine fault tolerance mechanism is a kind of adoption & quot; Permission to vote, minority subject to majority & quot; The consensus mechanism allows Byzantine fault tolerance, allows strong supervision nodes to participate, has the ability of authority classification, higher performance and lower energy consumption, and each round of bookkeeping will be jointly elected by the whole network nodes, allowing 33% of nodes to do evil, and the fault tolerance rate is 33%. Practical Byzantine fault tolerance is especially suitable for the application scenario of alliance chain<
advantages
will deviate from centralization, the existence of cryptocurrency and reward mechanism will proce Matthew effect, making the poor poorer and the rich richer in the community, achieving high consensus efficiency and realizing high-frequency trading
disadvantages
when only 33% of the nodes in the system are running, the system will stop running
dbft authorizes Byzantine fault tolerance
this mechanism is to use rights to select bookkeeper, Then bookkeepers reach a consensus through Byzantine fault-tolerant algorithm. The core of Byzantine fault tolerance mechanism is to ensure the system's finality to the maximum extent, so that the blockchain can be applied to real financial application scenarios
advantages
Professional bookkeeper can tolerate any type of error, bookkeeping is completed by multiple people, each block has finality, no bifurcation, the reliability of the algorithm has strict mathematical proof
disadvantages
when one-third or more bookkeepers stop working, the system will not be able to provide services, when one-third or more bookkeepers jointly commit crimes, The system may be bifurcated
pool verification pool
based on traditional distributed consistency technology and data verification mechanism
advantages
it can work without cryptocurrency. Based on the mature distributed consistency algorithms (pasox, raft), it realizes second level consensus verification
disadvantages
the degree of decentralization is not as good as bitcoin, which is more suitable for the multi center business model with multi participation
Paxos
this is a traditional distributed consensus algorithm, which is a consensus mechanism based on election leaders. The leader node has absolute authority, and allows strong supervision node to participate, which has high performance and low resource consumption. Generally, all nodes have wired access mechanism, but there is no malicious node in the election process, which is not fault-tolerant< In Paxos algorithm, nodes are divided into three types:
proposer: put forward a proposal and wait for everyone's approval. The client often plays the role
acceptor: responsible for voting on the proposal. Usually, the server plays this role
learner: is informed of the result of the case settlement, and unifies with it, and does not participate in the voting process. Maybe the client or server
Paxos can ensure that the system can reach a consensus when more than 50% of the normal nodes exist
REBO consensus mechanism
REBO consensus algorithm enables a group of nodes to form a consensus based on the special node list. The initial special node list is like a club. To accept a new member, it must be voted by 51% of the members of the club. Consensus follows the & quot; 51% rights;, Outsiders have no influence. Since the club starts with centralization, it will always be, and if it starts to corrupt, shareholders can do nothing. Like bitcoin and peercoin, the reborn system separates shareholders from their voting rights, so it is more centralized than other systems
peercoin
peercoin (PPC) is a combination of proof of pow workload and proof of POS equity. POW is mainly used to issue currency. In the future, with the increase of mining difficulty, the output will decrease, and the system security will be mainly maintained by POS
in the blockchain network, e to different application scenarios, different goals are designed, and different blockchain systems adopt different consensus algorithms. Each consensus algorithm is not perfect and has its own advantages and limitations
blockchain solves the problems of transmitting trusted information and value transfer on untrusted channels, while consensus mechanism solves the problem of how blockchain achieves consistency in distributed scenarios
although the blockchain is still in the early stage of development, and the instry development is still facing some obstacles, the society has recognized the value of the blockchain enough, the pace of blockchain development will never stop, and the instry development will certainly find a way to break through the obstacles.
